He volume of a sphere is 4/3πr3, where π has the value of "pi" given in Section 2.1 of your textbook. Write a function called print_volume (r) that takes an argument for the radius of the sphere, and prints the volume of the sphere.

Call your print_volume function three times with different values for radius.

Include all of the following in your Learning Journal:

The code for your print_volume function.
The inputs and outputs to three calls of your print_volume.

Part 2

Write your own function that illustrates a feature that you learned in this unit. The function must take at least one argument. The function should be your own creation, not copied from any other source. Do not copy a function from your textbook or the Internet.

Include all of the following in your Learning Journal:

The code for the function that you invented.
The inputs and outputs to three calls of your invented function.
A description of what feature(s) your function illustrates.

The programs below calculated the volume of a sphere and the square root of any given value. The functions are written in python 3 thus :

import math

#import the math module

def vol_sphere(radius):

#initialize a function that takes a single argument

return (4/3)*math.pi*radius**3

#returns the volume value of a sphere

print(vol_sphere(4))

print()

print(vol_sphere(6))

print()

print(vol_sphere(8))

print()

2.)

def sqroot(val):

#initialize a function that calculates the square root of a number

return val**0.5

print(sqroot(4))

print()

print(sqroot(25))

print()

print(sqroot(64))

Sample runs of the programs are attached.

1) # function to print volume of a sphere

  def print_volume(radius):

   volume= (4/3)*3.14*radius*radius*radius

   print("Volume:{0}",volume)

print_volume(4.23)

print_volume(4.34)

print_volume(12.34)

Output:

Volume:{0} 316.8761018400001                                                                                                  

Volume:{0} 342.24536341333334                                                                                                  

Volume:{0} 7867.085384746666    

2) # area of square calculator

def print_area(length):

   area=length*length

   print("Area of Square{0}",area)

print_area(4.23)

print_area(4.34)

print_area(12.34)

Output:

Area of Square{0} 17.892900000000004                                                                                          

Area of Square{0} 18.8356                                                                                                      

Area of Square{0} 152.2756

Explanation:

We have created two functions, first to calculate the volume of a sphere. and second to calculate the area of a square. Remember pi=3.14.
